ELECTRO SLAG REMELTING
An ESR under Ar, N2 gasses, to prevent gas absorption, with the annual capacity of 6000 Tons high purity ingots exists in the steel making section. Generally, ESR to produce ingots with high level of compositional & elemental homogeneity and at the same time to achieve high purity product.
ESR consists of three melting stations that makes it capable of producing ingots with 6000 mm length, 1200 mm diameter in central shaking mold. Also ingots with 2700 mm length, and 900 mm diameter can be produced in extra fixed molds
